which one should be better to get

no one ? opinions

If you want GPS get the 940 or the z140

8400 has no GPS but you can buy an add on that will give you GPS with limited points of interest 400,000 vs 12 million in the 140/940

iether way you are gona have to wait a few months untill the 940 comes out

but yeah if you want GPS get the X if you jsut want dvd then go for the P

I have the 8400bh. When i use the advanced app mode i get the maps app from my iphone which works perfectly for me. there is also another app called extra mile that is free that will give you turn by turn direction. I chose the 8400 to still get the navi without paying the navi money. Plus its a 7in screen.

i would personally get the 940 for the sole reason that is doesnt have a moving face, which is the most likely thing to break for units that do have moving faces.
